Based on the secondary development of the established excavator platform, SWDR138 cutting rig is equipped with effective and efficient propelling, rotation, dedusting devices, and screw-type air compressor, achieving fast cutting or impacting of the rock; when provided with an excavation device, it would be a complete excavator, and thus the same machine can be used for three purposes. SWDR138 cutting rigs are used for drilling and blasting in engineering and mining. It fully replaces a combination of separate machines, which increases working efficiency by times and greatly reduces the operation cost.
▲ Fast and large-torque rotary cutting; screw-type air compressors with high pressure and large air flow provide strong power during the drilling of rocks.
▲ Automated extension and removal of drill rods allows for the drilling of deep holes and greatly improves the working efficiency.
▲ The two-stage dry dedusting system and the unique anti-thrusting mechanism effectively reduce dust and maintain a clean working environment.
▲ The rotation and propelling are adaptive to the change of rock layers through the hydraulic pressure, which effectively improves the drilling efficiency, and prevents the rig from jamming.
